Abstract
An apparatus including a control cylinder rotatably supported for thermal conduction to a sheet. The sheet conveys ink deposited on a first side. The sheet is held against a peripheral arch of the control cylinder as it rotates with the first side of the sheet directly engaging and wrapping around the control cylinder along the peripheral arch. The apparatus also includes a thermal control element for heating and/or cooling the control cylinder. The apparatus also includes a pressure roll for spreading the ink. The pressure roll with the control cylinder forms a spreader nip, which is selectively changeable between a closed and open position. In the closed position the pressure roll is biased toward the control cylinder for applying pressure to the ink on the sheet. The pressure roll is spaced further away from the control cylinder in the open position relative to the closed position.
